Correct output but incorrect answer

I am not sure why this answer is not correct. I have submitted support as I thought it was a bug but they say other people was able to pass the test so I might be missing something

string_factory.py 
def favorite_food(name, food):
    print ("Hi, I'm {} and I love to eat {}!".format(name,food))

favorite_food(**{"name":"Jin", "food":"Bacon"})

Key part is: 

Your function should unpack that dictionary

Remember, that using curly braces with strings, you can refer to your variable substitutions by name and use them in any order you want.

"Hi, I'm {name} and I love to eat {food}!".format()

And you can use double asterisks to unpack dictionaries (keyword arguments).

def unpack(dictionary):
  return "{I} {am} {num} {a} {dictionary} {num}".format(**dictionary)

print(unpack({'I': 'yo', 'am': 'soy', 'a': 'un', 'dictionary': 'dictionario', 'num': 5}))

# yo soy 5 un dictionario 5

Ah I see more clearly how unpacking is done now. Thanks a lot!
